    HC110 made simple.

    I thought I had posted this to the articles a long time ago, but I guess I didn't. So for the archives and the children, here it is.

    I like Hc110. Especially for roll film. I don't like the convoluted "working
    solution" dilutions and sub dilutions, or the short times some of the dilutions
    and sub dilutions create. It should be simple to use Hc110, like Rodinal.

    If you care to research, there was a method to Kodaks madness when they
    created the dilutions and routines for HC110, but they are of little
    convenience for the darkroom enthusiast. I get more questions about
    mixing and developing with HC110 than all other developers combined. It is
    a great developer that doesn't need to be complex in usage, so I concocted a
    metric dilution that goes by 50 (1+49) That means you use 1 ml of HC110 for
    every 49 ml of water in a direct from the concentrate dilution.

    Here is how to use it on roll film in an inversion tank, like Rodinal:

    First of all, forget about saving and replenishing it. Mix up what you need, use
    it, and dump it. It's so cheap under normal usage that saving it is fairly
    useless from a cost savings perspective, plus consistent performance is
    assured by using it one-shot.

    Next, forget about an intermediate working solution. Mix it directly from the
    concentrate. Use a small bottle and a baby syringe (available at any drug
    store) to mix directly from the concentrate. Simply mix it 1+49 . Use the times
    below as a starting guide (you may not expose the same as me, or may not
    have the same taste in negatives, so these are only suggestions that should
    get you in the ballpark to do your own tweeking)

    So without further ado,

    Hc110 direct from concentrate-1+49 , 68f 20c, agitate first 30s with 2
    inversions every 30s thereafter.

    ****Note to the civilized-Please keep in mind that this methodology is for the
    US version of the concentrate*****

    Acros100 @ 100 - 8 min

    A friend of mine in Texas says that in the Summer, he hooks up his well to the hot water pipes, turns off the gas to his water heater, and hooks it up to the cold water pipes. The water heater's inside his air-conditioned farmhouse.

    Ever been to Texas, Stone?

    has anyone tried Delta 100 @100 with this dilution? 8 minutes? 9 minutes? I have no idea about the Delta emulsions as I normally use Acros 100. thanks.

    From the North American concentrate, I use a syringe (without the metal needle) to suck up 15ml of hc110. I squirt it into 1500ml of water, @ 20C, in my Patterson tank. It takes 5 rolls of 35mm or 3 rolls of 120 film. 1 minute initial agitation, then 1 minute agitation after 20 minutes, dump after 40 minutes. Easy-peasy!

    I'll suck up water/developer into the syringe to rinse it out into the developing tank to get it all.

    thanks Frank, but I am hoping to find a time for this 1+49 dilution for Delta 100. I suppose I could just try 8 minutes and see what happens? Delta 100 is now cheaper than Acros 100 (seems like just yesterday Acros was $3 and change) so thinking of making the switch, though it'll be a bit more of a pain for long exposures.

    Sorry, I was responding to this thread in general, not your post in particular.

    Huh? 1500ml in a 1L tank? Confused...

    Are you sure? Doesn't a single roll of 35mm film need 290ml to cover it?
